15.7 Partial pooling

  • Example results (we will see how to do this next week)
Posterior median models of the no pooled (blue), complete pooled (black), and hierarchical (dashed) models of running time vs age for three example runners and you.

Figure 15.1: Posterior median models of the no pooled (blue), complete pooled (black), and hierarchical (dashed) models of running time vs age for three example runners and you.

  • Note the fit no longer predicts the first runner getting better with age.. information from other runners informed this fit.

  • Also note that partial pooling allows us to make predictions for new groups… like YOU!
